Improvement in car-springs



LEWIS VOTE, OF PITTSBURG, PENNSYLVANIA.

IMPROVEMENT IN CAR-SPRINGS.

Specification forming part of Letters Patent No. 132,879, dated November5, 1872.

To all whom it may concern:

Be it known that I, LEWIS VOTE, of Pittsburg, in the county of Alleghenyand State of Pennsylvania, have invented a new and Improved Spring forCars and other Vehicles; and I do hereby declare the following to be a.full, clear, and exact description of the same,

reference being had to the accompanying drawing forming part of thisspecification, in which- Figure lis a side elevation of my improvedspring, shown partly in section; Fig. 2 is a vertical section in theline as m, Fig. 1; and Fig. 3 is a topplan view.

Similar letters of reference in the accompanying drawing denote the sameparts.

The object of my invention is to provide, for use upon cars and othervehicles, an improved spring which shall be uniform and easy ofoperation, which shall be protected against any lateral strains orwrenches of the carriage, and which shall cause the body of the carriageas it rises and falls upon the springs to move in a vertical line.

To the accomplishment of these several ends the invention consists inthe improved construction which I will now proceed to describe.

' In the accompanying drawing, A A are two levers, each constructed witha wide circular head, B, recessed upon opposite sides to receive thecoiled springs G. D D are supporting-plates, bolted or otherwise securedto the axle or other suitable part of a vehicle under the body. From oneplate of each set a lateral shaft, E, projects, whose outer end is heldto the opposite plate by a screw, F. Upon these shafts the heads of thelevers are mounted, the inner end of each spring being secured thereto,while the outer end is attached to the interior circumference of thehead. By this construction the heads and plates form closed drums, eachcontaining two coiled springs. The innerends of the levers overlap eachother, and are connected bya bolt, Gr, passingthrough ears H, projectingdownward from a swivelblock, I, upon which the body of the vehiclerests, the levers being slotted to accommodate the play of the bolt asthe vehicle springs up and down. The inclosing-cases, combined with thedrum-heads of the levers, cause the ends of the latter to move up anddown in a vertical line, and therefore impart an easy motion to thecarriage. Sudden strains or wrenches of the carriage in any directionare.

sustained entirely by the shafts E, and cannot, therefore, effect thesprings to injure them, so that their action'will at all times beuniform. The inclosing-cases effectually exclude all dirt and dust fromthe springs, and at the same time render the latter accessible for anypurpose. v V I do not confine myself to any special arrangement of thesprings upon a carriage,- as they may be placed in different positionsand yet accomplish the same result.

Having thus described my invention, what I claim is 1. A spring for carsand other vehicles, con

.sisting of two or more coiled springs inclosed between recessedlever-heads B and supporting-plates D, and connected by lever-arms A tothe body of the carriage, so that the latter shall rise and fall in avertical line, substantially as described, for the purpose specified.

2. The springs (J and the recessed levers specified.

LEWIS VOTE.
